Mine dropped to 1.023-24... What is the best way to calibrate a refractometer? I have heard just use RO water or to use a solution closest to your desired number.
SPStimie posted up the recipe awhile back, i think under the heading of refractometer calibration fluid.
you can check 0 with RO water but should also check it close to what your target readings should be to make sure its acurate.
I have some of the calibration fluid he mixed up, dont know how soon you need it though lol
Does anyone have the Neptune probe? I'm considering it, to pull top off water from a different location than the normal RO if salt is low. I wet skim so keeping at 35 is a chore.
I ended up tearing two muscles in my leg again back in November. For about 2 months, I was just high as hell. On painkillers that is. So I think I just kinda forgot about this place...lol. My reef went to **** while I was recovering...so I am now gonna take this time to reset it up as a full on Zeo reef. See what ya get for the benjamins.
